Transparent quantification of carbon intensity at the level of individual supply routes is essential for guiding investment, operational choices, and policy measures in the global effort to decarbonize energy systems. However, no study to date provides a comprehensive, route-level analysis of the end-to-end carbon intensity of liquefied natural gas. In this work, we assess every major liquefaction facility (n = 45), shipping corridor (n = 7 920), and regasification terminal (n = 190) worldwide, spanning 20 exporting and 45 importing nations. Route distances ranged from 36 km to 116 774 km (median 4 217 km), with cargo volumes between 1 080 t and 2 144 990 t (median 66 476 t). We calculate the carbon intensity of liquefaction (L: 0.06–11.76 g CO₂e/MJ), shipping (S: 0.8–38.99 g CO₂e/MJ), and regasification (R: 0.006–0.343 g CO₂e/MJ), yielding combined route-level-LSR intensities of 0.29–41.18 g CO₂e/MJ (median 3.71 g CO₂e/MJ). Our findings reveal pronounced variability driven by distance, plant efficiency, vessel type, plant and terminal operations. This granular transparency enables stakeholders to identify high-impact opportunities for emissions reduction, optimise route selection, and develop targeted decarbonization strategies for the global liquefied natural gas value chain.
